SUMMER COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 323,655, dated August4, 1885.

Application filed August 14, 1884. (E0 model.)

To all whom it may concern.-

Be it known that we, ED\VARD F. GORDON and Honii'rro HOBBS, citizens ofthe United States, residing at Concord, in the county of Merriniac andState of New Hampshire, have jointly invented certain new and usefulImprovements in Summer Cooking-Stoves; and we do hereby declare that thesame are fully described in the specification and illustrated in theaccompanying drawings.

The object of this invention is to provide an acceptable non-radiatingsummer cookingstove as a substitute for the ordinary cookst-ovc and themore objectionable oil and gasoline stoves, all of which classes radiate(and therefore waste in hot weather) a large percentage of the heatgenerated by combustion.

The invention consists in certain peculiarities of construction andcombinations of parts, hereinafter pointed out and claimed. Thecombination, form, and arrangement shown are, however, original with us,and are advantageous in respect to convenience in use and to economy infuel, and are therefore claimed as a part of our invention.

The drawin s re resent the best form in which we have contemplatedapplying our invention, Figures 1 and 2 being, respectively, side andend elevations of our improved stove mounted on legs and provided with ahorizontal shelf connecting them. Fig. 3 is a longitudinal section ofthe stove without legs. Figs. 4 and- 6 are transverse sections of thesame on the lines :0 and y, and Fig. 5 is a top plan.

In the drawings, A is the body of the stove, preferably in the form ofan elongated drum having a flat top and bottom. This drum may be mountedupon legs B, connected horizontally by a shelf, 0, as in Figs. 1 and 2;or the legs may be omitted, as in the sectional views, and the stoveplaced upon any suitable sup- )ort.

l The non'conducting filling or packing D is shown in Figs. 3, 4, and 6as interposed between the outer metallic shell, E, and the inner one, F,which are perhaps an inch apart. For this packing we prefer thesubstance known as mineral wool or mineral conton, which is bothnon-conducting and incornbustible, and has the merit of beinginexpensive and easily worked. lVit-h this mate rial we fill all thespaces between the shells E and F, thus furnishing a packed double wallfor the sides, bottom, and both ends of the stove.

G is the cast-iron top of the stove having two griddle-holes and aflue-opening in it.

H is the fire-pot, with a swinging grate at, its bottom, and in thespace below this we place an ash-pan, which may be reached by openingthe end door, I. Fueleither coal, coke, or hard wood-is supplied to thefirepot through the griddle-hole, and the draft is regulated by a slide,K, Fig. 2. L is a trans verse cast-metal partition separating the firepot from the oven 0. The oven-door J is shown at the rear end. In theoven is a grate or rack, 1.

We form the oven as a sheet-metal cylinder, (shown in Figs. 3 and 6,)its ends being the partition L and the rear door, J. The caloric currentpasses entirely around this oven in the annular space between it and thepacked walls, a guard or fender, M, and damper N (shown in dotted linesin Fig. 5) preventing its direct course to the fine. The damper maybeturned down to open a direct draft by a rod, B, Fig. 5.

The annular space for the caloric current is indicated by the letter S.Soot and ashes may be dislodged from its walls by a wire or flexible rodor brush introduced from above. A pivoted door, T, permits removal ofsuch matter at the bottom through the ash-space. (See Fig. 4.)

Many advantages follow the construction shown. The nearly cylindricalform of the stove-body with the annular flue around the oven utilizesthe fuel, heats the oven very speedily, and promotes the draft by givingthe caloric current an unobstructed course in curved lines, instead ofbeing frequently deilected' at right angles, as in the usual form ofstoves; and as the current, in passing entirely around the oven, movesforward from the fire pot to the funnel, it takes a generally helicaldirection, and does not deposit soot and ashes to such an extent as inthe common rectangular stoves. The fire-pot is surrounded by a hotairspace, and is detached from the transverse partition, so that the entireend of the oven is heated quite un1formly by radiation, and notintensely at one point by conduction, as in.

ICO

stoves having the fire-pot in contact with the oven-wall.

We claim as our invention 1. A cooking-stove having unpacked top andgriddle-holes in its top, and the remainder of its body packed to resistradiation by a filling of mineral wool or other non-conducting materialbetween two metallic shells, as set forth.

2. A packed cooking-stove having an inclosed fire-pot near one end, withan ash-door in said end, an interior oven with its door at the oppositeend of the stove-body, and an annular space for the caloric currentbetween the oven and the packed outer wall, as set forth.

3. A stove having a substantially cylindrical body with a flat top, afire-pot at one end,

an interior oven, and a flue leading from the fire-pot entirely aroundthe oven to the funnel, so as to give a generally helical movement tothe caloric current from front to rear of the stove, substantially asset forth.

4. A stove having a substantially cylindrical body with a flat top, afire-pot at one end, and an interior oven, a flue leading from thefire-pot entirely around the oven to the funnel, and a covered openingfrom said flue through the partition which separates it from theash-pit, to provide for cleaning said flue, substantially as set forth.

In testimony whereof We hereto affix our signatures inpresence of twowitnesses.
